The automotive industry is evolving toward connected and autonomous vehicles that offer many benefits, such as improved safety, less traffic congestion, reduced environmental impact, and lower capital expenditure. With the trend to equip vehicles with 3GPP Release 14 C-V2X ECUs, peer-to-peer data transfer in ad-hoc networks between vehicles will be established. The vehicles share location, speed and trajectory, enabling warnings regarding on-road dangers to be shared between drivers. Applications cover use cases such as vehicle-to-vehicle (V2V) communication, data exchange with roadway infrastructure (V2I), and interaction with vulnerable road users such as pedestrians (V2P). Data communication is implemented in the 5.8 GHz and 5.9 GHz intelligent transportation system (ITS) spectrum bands.
Both partner companies have already demonstrated a solution designed to configure and run traffic scenarios to comprehensively test the physical layer 3GPP Rel. 14 up to the application layer of C-V2X ECUs. For the test solution, R&S has expanded the capabilities of its R&S CMW500 LTE network simulator and R&S SMBV100A/B GNSS simulator to interoperate with Vector CANoe .Car2x, a software tool for simulation, development and test of V2X-based communication applications. The solution enables engineers to verify critical end-to-end safety-related V2X scenarios in a lab environment.
